1) Physical & Astronomical Constants - press to include into a calculation or long press for more information on the constant and its relationship to other constants

2) Periodic Table - a full listing of the periodic table - press to input an element's atomic mass into a calculation or long press for more information on the chosen element - the app also includes a clickable, pictorial representation of the periodic table

3) Solar System - press to input a planet's orbit distance into a calculation or long press for more information on the chosen planet

4) My Constants - a set of personal constants that can be added via the History

* Convert between hex, oct, bin & dec

* AND, OR, XOR, NOT, NAND, NOR & XNOR Functions

* Left Hand & Right Hand Shift

* Plotter with a table also available together with the graph

* Complex numbers in Cartesian, Polar or Euler Identity format

* The main screen of the calculator can also be set to Fractions Mode for general arithmetic functions including use of parentheses, squares, cubes and their roots

* 20 Memory Registers in each of the calculation modes

* A complete record of each calculation is stored in the calculation history, the result of which can be used in future calculations

An extensive help facility is available which also includes some useful scientific reference sections covering names in the metric system, useful mathematical formulas and a detailed listing of physical laws containing a brief description of each law.

A default screen layout is available for each function showing all buttons on one screen or, alternatively, all the functions are also available on a range of scrollable layouts which are more suitable for small screens - output can be set to scroll either vertically (the default) or horizontally as preferred â€“ output font size can be increased or decreased by long pressing the + or - buttons

A full range of settings allow easy customisation - move to SD for 2.2+ users

Please email any questions that are not answered in the help section or any requests for bug fixes, changes or extensions regarding the functions of the calculator - glad to help wherever possible.
